ZIP code 61431

ZIP 61431 is a very small community in Fulton County, Illinois, with 283 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1232 of 1,396 ranked by population — larger than 11% of them. The median age here is 54.1 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in ZIP 61431 earn a median of $51,058 a year, 35% below the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 7.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 61431 is valued at not published, while median gross rent runs not published a month. 91.7% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 54.1 puts ZIP 61431 well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 283 residents, a handful of survey responses moves every median on this page. Compare ZIP 61431 against its county rather than against national figures.

The Census withheld home value, gross rent for ZIP 61431 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.

Illinois charges 6.25% statewide, and local governments overlapping 61431 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 61431 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
